ABSTRACT
The statutes associated with the County Sanitation District Act of 1923 permitted the creation of sanitation districts to treat and dispose of wastewater on a regional basis, generally according to logical drainage areas, irrespective of city boundaries. In the central service area, 15 sanitation districts operate as the Joint Outfall System to service over 9,000 industrial companies and about four million people. Certain sections of the Joint Outfall System service area contain significant industrial development. The industrial waste engineers are also responsible for coordinating the effort to implement those Federal categorical pretreatment regulations within their assigned area of expertise. The intent of the national Environmental Protection Agency pretreatment regulations should be the intent of all local industrial waste pretreatment programs. The effectiveness of an industrial waste regulatory program is at least partly dependent upon the effectiveness of the enforcement program. Inspection of industrial companies is necessary to ensure compliance with industrial waste regulations.
